Using alot of fuel at normal drives.

[john182rs]

I filled my car yesterday to the brim, and today its saying ive used 1/4 of a tank or 2 gallons on the trip. Ive only done 40 miles. So 20 mpg on normal driving.

Any suggestions on what this could be as i have not got a clue.

Someone been syphoning your petrol?

 

[AK]

Someone been syphoning your petrol?

Either that or low tyre pressure??

 

[DrR]

what car? If a 182 do a full tank run, should get 300ish miles IMO

 

[edde]

best drive some more before checking

 

[john182rs]

Tyres are what some one on here recommended me.. F=32 R=28
Its a 182 and the last full tank got me roughly 250 miles. Thats driving to and from work 5 days a week (150 miles) then i usually do a long drive at 50 to 60 mph on the A roads.

cold weather will affect your mpgs a bit...

 

[john182rs]

what a full 12mpg bit for cold weather, i used to see 32 to 36 mpg.

 

[DrR]

My 172 would do 250 miles tops on a tank of fuel, 182 does 300ish easy.

 

[Jamesl172]

i use to get around 32 but recently been getting 24mpg - annoying but iv been doing loads of short journeys + cold weather = too much money on petrol.

 

[LegoHead]

Could it be down to loads of really cold starts?

 

[Luke.]

im seeing about 26 atm and thats with decat and no map!

used to get 30+

 

[Little Newms]

Will be the weather.... There like an american V8 on start up. Gulp gulp gulp!

 

[leekirlew]

Nah i reckon you will be fine mate. If you dont "brim" it a lot you wont have noticed this. but for some reason (dont ask me why lol) i find that the 1st 1/3 of a tank goes in like 60 miles, then the next 1/3 last an eternity and then the last 1/3 is sort of normal, its as if they made a trapeze fuel tank lol

Btw i always use v-power or an equivalent so im used to seeing 30mpg + town driving (some hard driving) and 37 - 42 on a nice steady journey, totally standard motor

 

[caister]

Could be the O2 Sensor?

I'm still getting 350miles out of a tank even in this wheather.

 

[Fletcher]

My mpg hasn't dropped that much, in the recent cold snap.

 

[bmh.01]

You can't use the gauge as a reference, its not linear. The top 1/3 or stop drops really quick then it hangs around in the middle for ages.

 

[platty]

getting around 25mpg around town.... got 38mpg on a 40 mile trip today which i was pleased about.

 

[Nafeun]

the cup does 320 hardish miles to a tank

+1

 

[john182rs]

It used to stay at the top for ages then drop down, put it this way its now reading just below half a tank.
Think ill get GDi to check it over properly.

My 1.2 sees about 38 in the summer as an average, with it topping 48 on a long run.

I was getting 28.3 the other day ffs. Filled it up with v power and im back to 33.4 mpg now.

 

[jester2k]

Is it sitting on your drive warming up for ages, then a short drive to work?

MY cup (even with warm ups 10mins) is seeing about 34 at the mo

 

[SpaceMonkey]

I reset my MPG @ my last fill up & although my trips are short I'm only seeing 22MPG @ the mo

 

[Mostro]

Me too. Cold starts and 3 mile city commutes......

Average mpg: 22mpg
Average mph: 20mph :dapprove:

:boring:

 

[Thornesy]

My 172 (Completely standard) shows 320 miles when brimming on the trip computer.. I commute 14 miles round trip and at the moment i'm getting 27.9 mpg which has gone down since the cold weather came..

SNAP! It's like the first 1/3 of a tank lasts about a day, then the car seems to be half full all week.

As I said last night fat lad, I'm getting about 33-35mpg on runs to work at the moment. That's less than normal - I usually get 38-40 but like other people have said, it's cold weather.
I ragged it some of the way home last night and still averaged 25.3mpg.

 

[john182rs]

No srtanding, i get in the car start it up an then drive 15 miles to work on long roads doing 40 on average. Then i do the same coming back start up and drive same route back. Im on roughly a 1/4 of a tank now and i filled up on sunday night.

 

[DMS]

I thought there was a fairly strong smell of petrol when you started the car up last night to reverse out of the garage. Over-fuelling?

 

[sideways danny]

as i said on the phone earlier, probably lambda sensor. Seen loads fail on 182s recently, odd. Easy enough to check out on diagnostics when you bring it down

 

[172Dom]

I have NEVER seen higher than 27mpg on mine.....:S
And when i do put V.power in it drops to 22mpg and burns the whole lot in a flash!!! whats happening????

 

[Laura]

mines killing me atm, 27mpg used to be 32ish

 

[sideways danny]

swap lambda for the post cat one. you'll get a brand new one with your ITBs soon anyway

 

[john182rs]

Danny is it confirmd for the 17th or 24th yet?

 

[PinkoCommie]

I seem to be averaging 1 or 2 mpg less than usual on my work run since the cold snap started, but I suspect that might have something to do with me putting a RSTuner Ron98 remap on it

Tesco 99Ron all thway though.

 

[Blue4Ever]

I seem to get around 300-350 or roughly 100 miles to a £10er
That's in a 1.4
I'm with you on the first 3rd of the tank going down quickly!
